Frequently Asked Questions

What is 316L stainless steel, and why is it better for water bottles?
316L is medical-grade (surgical-grade) stainless steel containing molybdenum for superior corrosion resistance. Unlike standard 304 steel used by most brands including Yeti and Hydro Flask, 316L won't leach metallic flavors into acidic beverages like coffee, juice, or sparkling water. It's the same alloy used in surgical implants and marine equipment — chosen specifically for its purity and durability.
What's the difference between 316L and 304 stainless steel?
304 stainless steel is a solid general-purpose grade, but it can release trace metals when exposed to acidic liquids over time. 316L adds 2–3% molybdenum, which dramatically improves resistance to pitting and crevice corrosion. The result: a cleaner taste, longer lifespan, and safer daily hydration — especially if you drink coffee, lemon water, or carbonated beverages.
How does the no-screw lid work?
Our patented Revomax no-screw lid uses a 3-button release mechanism. Press the buttons and the cap pops open instantly — no twisting, no threading. You can open and close one-handed in under 2 seconds, making it perfect for driving, cycling, hiking, or any situation where you only have one free hand.
How long do these bottles keep drinks hot or cold?
Double-wall vacuum insulation keeps beverages cold for up to 36 hours and hot for up to 18 hours. We've tested in extreme Canadian conditions, including –40°C winters and hot car interiors in summer — ice cubes stayed frozen after a full day in a sun-baked vehicle.
Are these bottles dishwasher safe?
The 316L stainless steel bottle body is dishwasher safe. We recommend hand-washing the no-screw lid to preserve the seal mechanism and extend its lifespan. A quick rinse with warm water after each use keeps the lid performing like new.
Which size should I choose?
9 oz — compact travel or kids' bottle
16 oz — ideal for commuting and everyday carry
20 oz — our #1 bestseller with 63+ five-star reviews, perfect for all-day hydration
32 oz — built for workouts, long hikes, and full-day adventures

All sizes use the same 316L medical-grade steel and no-screw lid technology.
